Custom Forged Blocks, Rectangles & Flats

Forged alloy steel blocks are created through a manufacturing method that utilizes localized compressive force shaping processes. The process begins when steel blocks are compressed within a die and custom shaped to exact project specifications. Custom forged steel blocks are available in flat and rectangle form and are commonly used in several industries, including aerospace, food processing, chemical, oil & gas, and defense.

What are Forged Steel Blocks?

Forged alloy steel blocks are considered a raw supply product, even though they have been extensively worked and refined to improve the properties of the metal. The blocks themselves are not a finished product; instead, they are used by machine shops and manufacturers to create a finished part.

Stainless steel forging block is valued for several beneficial performance advantages it provides in high-pressure environments, applications in which corrosion resistance is essential, and any application in general that requires greater strength or longer life out of the finished parts.
